Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a substrate treating device for dealing with the increased size of a substrate by supplying treating solution to the surface of the substrate, generating an elastic progressive wave on the surface of the substrate, and using this as a driving source to move the treating solution on the substrate. SOLUTION: Treating solution such as resist, developing solution or the like is supplied onto a substrate and, when an elastic advancing wave is generated in the vicinity of the surface of the substrate, the treating solution is moved in the direction opposite the progressive direction of the elastic progressive wave, and thus the treating solution is spread on the surface of the substrate without rotating the substrate at a high speed. According to a driving principle, an object OB is placed on a vibration surface VS, and the elastic progressive wave excited by ultrasonic vibration is progressive in the right direction. At this time, each point on the vibration surface VS draws an elliptic track counterclockwise. The object OB is driven by the movement of this track to progress in the left direction.  The surface of the substrate is used as a vibration surfaced VS, and the treating solution as the object OB on the substrate is driven by the elastic progressive wave on the substrate surface.

Title: Up and down vibration control construction
Inventor: KIKUKAWA HITOSHI
IPC: E04B1/98
Filed: 1993-04-09
Abstract: PURPOSE:To control vibration of disturbance of various frequencies effectively by bearing the end of a horizontal member on a pin roller and, at the same time, providing a viscous body between a vertical plate extended from the end of the horizontal member and a column. CONSTITUTION:For example, the end of a longer span of a beam 10 provided to a broad space such as an office, etc., is bone on a pin roller through a bearing projection 12. Vertical plates 13 are approximately vertically fixed to both ends of the beam 10. In addition, the vertical plates 13 are held between columns 11 through viscous bodies 14. When disturbance of various frequencies is applied to the beam 10, first of all, disturbance energy is directly transferred to the vertical plates 13. After that, vibration caused by the disturbance energy is absorbed by shear deformation of the viscous body 14 between the column 11 and vertical plate 13 and is dispersed. Accordingly, an energy extinction amount per unit area can be increased by the vibration control construction.

Title: Discriminating device for recordable area in optical disk device
Inventor: ARAKI MITSUHIRO
IPC: G11B7/00
Filed: 1987-04-06
Abstract: PURPOSE:To correctly recognize a DC recording sector as a recorded sector, by rendering decision by processing a light receiving level signal including a DC component which senses to the fluctuation of the low frequency of a light receiving level. CONSTITUTION:When an optical head scans a sector whose sector is separated, the light receiving level signal is obtained from an adding amplifier 2. The size of the light receiving level signal senses to the fluctuation of the low frequency of the light receiving quantity of an optical detector 1, and the difference of reflectance due to the difference of the surface states of an optical disk in recorded, unrecorded, and DC-recorded is reflected almost with fidelity. A sample timing generation circuit 5 controls a switch 4, and makes a sample/hold circuit 3 hold the voltage V2 of the light receiving level signal 21 from a record prohibiting area. As a result, a differential signal is outputted from a differential amplifier 6. Therefore, the differential output reflects the difference of a reflected light quantity due to the difference of the recording states of the optical disk correctly. In such a way, it is possible to discriminate a recordable area by discriminating the level.
